Multiple Choice

All of the following are functions served by phosphatidylinositol bisphosphate EXCEPT:

Phosphatidyl inositol bisphosphate can be hydrolyzed to produce diacylglycerol, a second messenger.

Phosphatidyl inositol bisphosphate can be hydrolyzed to produce inositol trisphosphate, a second messenger.

Phosphatidyl inositol bisphosphate can serve as the substrate to phospholipase C.

Phosphatidyl inositol bisphosphate will serve as a docking site for proteins containing a SH2 domain.

Verified step by step guidance

Understand the role of phosphatidylinositol bisphosphate (PIP2) in cellular signaling. PIP2 is a phospholipid found in the plasma membrane that can be hydrolyzed by the enzyme phospholipase C (PLC).

Recognize that when PIP2 is hydrolyzed by PLC, it produces two important second messengers: diacylglycerol (DAG) and inositol trisphosphate (IP3). These molecules play crucial roles in signal transduction pathways.

Identify the common functions of PIP2: serving as a substrate for phospholipase C, and being involved in the production of DAG and IP3, both of which are second messengers.

Consider the role of SH2 domains. SH2 domains are protein domains that bind to phosphorylated tyrosine residues on other proteins, typically involved in signal transduction pathways. PIP2 is not known to serve as a docking site for proteins containing SH2 domains.

Conclude that the statement 'Phosphatidyl inositol bisphosphate will serve as a docking site for proteins containing a SH2 domain' is the exception, as PIP2 does not perform this function.
